1EDI60N12AFXUMA1 Overview
A gate driver IC is a power-management semiconductor that sits between a low-voltage control signal (such as a PWM output from a microcontroller or DSP) and the gate of a high-voltage power switch (MOSFET, IGBT, or SiC). Its primary job is to provide the high peak currents needed to charge and discharge the large gate capacitance quickly, which minimizes switching losses. Galvanic isolation adds a high-voltage barrier between the control side and the power side, protecting low-voltage logic from dangerous high-voltage transients. Within the power-management hierarchy, gate drivers sit alongside voltage regulators, supervisors, and motor drivers as essential building blocks for any switched-power converter.
Key features include a wide VDD supply range from 3.1 V to 17 V, 120 ns typical propagation delay, 40 V absolute maximum output voltage, and 4 mm minimum creepage distance for reinforced insulation. The device supports input logic levels compatible with 3.3 V and 5 V microcontrollers and offers separate source and sink output pins that allow independent gate-resistor tuning for turn-on and turn-off transitions. Internal short-circuit clamping actively limits the gate voltage during desaturation events, protecting the driven MOSFET from over-stress.
The 1EDI60N12AFXUMA1 uses Infineon's coreless-transformer (CT) isolation technology, which provides robust reinforced isolation without the size, cost, or wear-out concerns of optical couplers. Compared with opto-isolated gate drivers, this architecture offers higher CMTI (common-mode transient immunity), tighter propagation-delay matching across temperature, and longer operational life. The integrated Miller clamp and DESAT-like protection further reduce the external BOM count in motor-drive and inverter designs.
Typical applications include industrial motor drives, solar inverters, UPS systems, welding equipment, induction heating, and EV onboard chargers. The high source/sink current capability also makes it suitable for driving high-current IGBT modules in traction converters.
When designing with this part, ensure the gate-drive loop is kept short and that a low-ESR decoupling capacitor is placed within 5 mm of the VDD pin. The separate source/sink outputs should each be routed with their own gate resistor to independently control rise and fall times.

Typical Applications
1EDI60N12AFXUMA1 is suitable for 6 applications: Industrial Motor Drives, Solar Inverters, Uninterruptible Power Supplies (UPS), Welding Power Supplies, Induction Heating Systems, EV Onboard Chargers.
Industrial Motor Drives
The 1EDI60N12AFXUMA1 is purpose-built for industrial motor drives driving 600-1200 V IGBT or CoolMOS half-bridges. Its 10 A source / 9.4 A sink capability rapidly charges multi-nC gate capacitances, reducing switching losses at high PWM frequencies (up to 100 kHz). The 1200 V working-voltage isolation with 4 mm creepage meets reinforced-insulation requirements for 400-690 VAC industrial mains, while the 120 ns propagation delay preserves PWM fidelity. Placed between the MCU/DSP and the inverter power stage, it provides the galvanic barrier essential for protecting low-voltage control electronics from high-voltage transients. Compared with opto-isolated drivers, the coreless-transformer design delivers higher CMTI tolerance, critical in noisy motor environments.
Recommended
Solar Inverters
In string and central solar inverters, the 1EDI60N12AFXUMA1 drives the high-side switches of the boost PFC and DC-AC stages operating at 600-1200 V. Its 3.1 V to 17 V VDD range accepts both 5 V logic from the digital controller and 12 V/15 V rails, simplifying power-tree design. The separate OUT (source) and SEP (sink) pins allow independent gate-resistor selection, so engineers can tune turn-on dV/dt to control EMI while keeping turn-off fast for low switching loss. Internal short-circuit clamping protects the driven MOSFET during desaturation events common in photovoltaic input surges, while the 4 mm creepage and 1200 V isolation rating clear UL 1741 and IEC 62109 safety requirements.
Recommended
Uninterruptible Power Supplies (UPS)
Online UPS systems rely on the 1EDI60N12AFXUMA1 to drive the high-voltage IGBTs in the rectifier and inverter stages that switch between mains, battery, and load. The driver's 10 A source / 9.4 A sink outputs handle the gate-charge requirements of large 1200 V IGBT modules, keeping switching transitions under 100 ns for high efficiency. The 1200 V working isolation protects the control DSP from mains transients during grid disturbances, while the 3.1 V to 17 V supply range simplifies integration with battery-derived 12 V or 15 V rails. Wide operating temperature range (-40 C to +125 C) suits the harsh thermal environment inside industrial UPS cabinets where forced cooling may be limited.
Recommended
Welding Power Supplies
Inverter-based welding machines, the 1EDI60N12AFXUMA1 drives the primary-side IGBTs of the high-frequency inverter that steps mains voltage down to welding current. Its 120 ns propagation delay and matched turn-on/turn-off timing ensure clean PWM at 20-100 kHz switching frequencies, which is essential for stable arc control and spatter reduction. The 1200 V isolation rating comfortably exceeds the peak rectified mains voltage of single-phase 230 V or three-phase 400 V inputs. The robust PG-DSO-8-51 package with 4 mm creepage handles the high-dV/dt noise typical of welding inverters, while the integrated short-circuit clamping protects IGBTs during arc short events that occur as part of normal welding operation.
Recommended
Induction Heating Systems
Induction cooking and industrial induction heaters switch at high frequencies (20-200 kHz) to drive resonant L-C tanks. The 1EDI60N12AFXUMA1's 10 A source current enables fast gate charging of 1200 V CoolMOS devices at these frequencies, minimizing switching loss and keeping efficiency above 95%. Its tight propagation-delay matching maintains the precise dead-time control required to prevent shoot-through in half-bridge resonant topologies. The 4 mm creepage distance clears IEC 60335 safety requirements for household induction cooktops. The wide VDD range (3.1-17 V) accommodates both logic-level and standard gate-drive supplies common in induction heating designs.
Recommended
EV Onboard Chargers
Onboard chargers (OBCs) for electric vehicles use the 1EDI60N12AFXUMA1 to drive the high-voltage PFC and LLC stages that convert AC mains to DC battery voltage. Its 1200 V working voltage handles the rectified 400 V or 800 V EV battery systems, and the reinforced isolation with 4 mm creepage meets IEC 61851 and ISO 6469 safety standards for EV charging. The 10 A source / 9.4 A sink capability rapidly switches CoolMOS or SiC MOSFETs at the high frequencies needed for compact OBC designs. Coreless-transformer isolation eliminates the aging concerns of optocouplers, important for automotive designs targeting 15+ year service life.

Key Differentiators
- Higher source/sink current than comparable isolated drivers (vs 1EDN6550BXTSA1)
- Galvanic isolation eliminates optocoupler aging (vs Traditional optocoupler-based gate drivers)
- Separate source/sink pins for independent rise/fall control (vs Most competing drivers with single output pin)
Design Notes
Place a low-ESR decoupling capacitor (1 uF ceramic minimum, 10 uF recommended) within 5 mm of the VDD pin (pin 5) to provide the high peak currents needed during fast MOSFET switching. Add a 100 nF high-frequency bypass cap in parallel. Route the OUT and SEP traces directly to the MOSFET gate, keeping the gate-drive loop area under 0.5 cmΒ² to minimize parasitic inductance that causes ringing and potential shoot-through.
At 100 kHz switching frequency driving a 20 nC CoolMOS gate charge, the 1EDI60N12AFXUMA1 dissipates roughly 0.4 W in the driver output stage. The PG-DSO-8-51 package has a thermal resistance of approximately 100 C/W, producing a 40 C junction temperature rise above ambient. Ensure copper pours on both GND2 and the exposed pad region (where present) to keep junction temperature below 125 C. Forced cooling is generally not required for normal operation but recommended in sealed enclosures.
Do not connect IN+ and IN- together; configure them per the datasheet truth table (typically IN- tied to GND1 for non-inverting operation, or IN+ tied to VCC for inverting). Avoid routing primary-side and secondary-side ground planes under the isolation barrier to maintain creepage. The 1200 V rating is the working voltage, not a transient rating; add TVS protection across the MOSFET drain-source if the application sees voltage spikes beyond the device rating.
